Still trying to found answer about the possibility to put 4 spot brembo caliper from F30 M sport car on my Z4 35is 348x30 rotors
Idea is to keep unsprung mass as low as possible but improve calipers.
From what I can read from realoem, 4 spot F30 caliper are 1.5kg lighter than Z4 35is one spot oem caliper.
Add some ECStuning lightweight rotor wich add 1.2kg gain per side and i could expect to gain up to 2.5kg of unsprung weight per side!!
That could make a difference in ride quality.
Please if someone has the answer, let me know.
